    Abstract: An electric window covering has a covering material, a driving device, a microcontroller, a position detecting module and a trigger detecting module. The position detecting module detects a position of a lower end of the covering material to generate a position information. The microcontroller compares the position information with a reference position to generate a position relationship with respect to the reference position. The trigger detecting module detects whether the covering material is moved by an external force for generating a detecting result. When the microcontroller determines that a trigger event is received according to the detecting result, the microcontroller configures the driving device to move the covering material according to the position relationship and the trigger event.

    Abstract: A window covering cutting apparatus includes a supporting base, a mounting base, a cutting device, a size positioning device, an input device, an output device, a storage device and a signal processing circuit. The signal processing circuit calculates acquired information including product information, a mounting mode, cutting size information and a position detecting value to generate adjusted position information and target position information, and displays them on the output device. The size positioning device is adjusted until the adjusted position information equals to the target position information, after which the signal processing circuit sets the cutting device to cut the window covering to the required size. Since a correct cutting position of the window covering is obtained by the calculation of the signal processing circuit, a risk of cutting the window covering to a wrong size due to miscalculation by users is reduced.

    Abstract: A window blind, wherein each ladder tape thereof includes two longitudinal cords, plural bearers and plural limiting members. The longitudinal cords each have an end connected to a deflecting mechanism disposed on the upper rail. The bearers are disposed between the two longitudinal cords for respectively supporting the slats. The limiting members include a first limiting member and a second limiting member neighboring thereto. The first limiting member has an end disposed on one of the longitudinal cords and includes a first slat-through portion located between two ends thereof passing through a first through hole of a first slat. A first linking loop is formed after the first slat-through portion passes through the first through hole. The second limiting member passes through the first linking loop for keeping the first through hole threaded through by one of the first limiting member and the second limiting member.

    Abstract: A charging system for an electric window covering, which includes a motorized assembly controlling the movement of the electric window covering, and a power supply device including a rechargeable power unit and a first remaining power detection circuit is disclosed. The charging system comprises a charging device which provides power to the power supply device, a comparison module, and a notification unit. The first remaining power detection circuit detects the potential magnitude of the power unit, and the detected value is transmitted to the comparison module to be compared. If the potential magnitude is less than a predetermined threshold, a warning is presented at a notification unit. By actively presenting the warning to the user when the power of the power unit is low, the power supply device and the charging system can achieve the objectives of providing an active notification and extending the run-time of the power unit.

    Abstract: A remote control used for opening and closing a covering assembly of an electric window treatment includes a main body, which includes a fixed unit, a rotating unit, and a detector. The fixed unit includes a first input unit which can be pressed. When the first input unit is pressed, it generates a first input signal to control the movement of the covering assembly. The rotating unit surrounds an external periphery of the fixed unit, and is rotatable relative to the fixed unit. The detector detects the rotation of the rotating unit relative to the fixed unit, and accordingly generates a second input signal to control the movement of the covering assembly. Whereby, a user can control the covering assembly in either way, and therefore the remote control is more flexible and convenient than conventional remote controls.

    Abstract: An adjusting module adapted for a window blind is disclosed. The window blind includes a headrail, a slat, a drum and a ladder cord. The drum and the ladder cord are disposed in the headrail. The ladder cord includes a first longitudinal cord, and is detachably connected to the drum. The slat is below the headrail. The adjusting module includes at least one protrusion member which is detachably disposed on the drum. With the first longitudinal cord passing around and contacting the first protrusion member, a length of the first longitudinal cord received inside the headrail is increased, and a length thereof between the bottom of the headrail and the slat is decreased, whereby to pull up a lower side of the inclined slat, so as to adjust the slat to horizontal.

    Abstract: A window blind includes a first rail, a second rail, a plurality of slats, a modulation mechanism, and an adjustment unit. The modulation mechanism includes a modulation shaft which can drive two warps of the ladder tape to make a relative movement in a vertical direction, whereby to modulate the slats to turn. When the slats are turned from a first position to a second position, the adjustment unit moves a rear cord which is used to move the second rail, whereby to change a length of a segment of the rear cord between a bottom edge of the first rail and a top edge of the second rail. In this way, the second rail could be turned along with the slats which are driven by the modulation shaft, and the problem of light leakage could be improved.

    Abstract: A position-fixing system includes a pole, a guiding member adjacent to the pole, and a movable member fitting around the pole. The pole is immovable relative to a window covering. The guiding member includes a principal axis parallel to an extension axis of the pole, and includes a retaining face substantially extending in the direction of the principal axis, but non-coplanar with it. The movable member corresponds to the retaining face. The movements of the movable member and the guiding member are related to that of a shaft of the window covering. When the window covering is being operated, the movable member is driven to rotate around the pole, and moves along the pole and the guiding member. Due to the retaining face, the movable member keeps contacting the pole to create a friction therebetween. Therefore, the position of a covering material of the window covering can be precisely fixed.

    Abstract: A window covering is disclosed, including a first rail, a second rail, and a shielding structure, wherein the second rail is movable between a high position and a low position through the driving of a cord, whereby the shielding structure can be raised and lowered. The first rail has a lifting mechanism provided therein, wherein the lifting mechanism includes a reeling device and a friction wheel. The reeling device is adapted to reel in or to release the cord, wherein the cord passes around and contacts the friction wheel. The cord provides a lateral pushing force to the friction wheel, pushing the friction wheel against a rubbed member to create friction, whereby to position the second rail accurately.

    Abstract: A control structure for a window covering includes a base, a revolving wheel having an axial post, a restriction means including a bushing fitting around the axial post, a transmission member provided on a side of the bushing, and at least one pawl connected to the axial post. The revolving wheel is connected to the base. The restriction means has at least one cutting groove. The transmission member has at least one abutting portion on an inner wall thereof. The pawl is pivotable within a width of the cutting groove. When the revolving wheel is rotated forward, an end of the pawl passes through the cutting groove to mesh with the abutting portion. When the revolving wheel is rotated backward, the pawl disengages from the abutting portion, and the transmission member is rotatable relative to the revolving wheel. Whereby, it could prevent generating noise while operating the window covering.
